Abstract

The reaction of some carbocyclic and heterocyclic Schiff bases with the synthesized 1-bromo, 4-[4-(4-nitrophenylazo) phenoxy] butane and formation of novel linear AZO-AZOMETHINE compounds in good to excellent yields were investigated. The compounds were fully characterized by UV-Vis, FT-IR, 1H NMR spectroscopic techniques and elemental analysis. Effects of various solvents on their visible ABSORPTION SPECTRA at a concentration of 10-5-10-6 M were estimated. The color of the dyes is discussed with respect to the substituent therein. Introduction of an electron-withdrawing group into the para-position of azomethines produces bathochromic shift of the absorption peak in all solvents. The key features of these reactions are, in turn, their operational simplicity, mild reaction conditions and easily-accessed starting materials.
